A Mathematical Model for Axial Length Estimation in a Myopic Pediatric Population Based on Easily Obtainable Variables

Photonics
Determining the axial length (AL) of the eye is of significant interest in the management of myopia. However, the devices that allow this value to be obtained are either expensive, for example, optical biometers, or inconvenient for use in pediatric ...

Comparative Study of Anterior Chamber Morphometrics Between Scheimpflug Tomography and Swept‐Source Optical Coherence Tomography

Journal of Ophthalmology, Volume 2026, Issue 1, 2026.
Purpose To compare the difference, correlation, and agreement of anterior chamber parameters measured by Pentacam and CASIA 2. Methods A total of 89 myopic patients (89 right eyes) of Beijing Tongren Hospital were included. Anterior chamber depth (ACD), anterior chamber volume (ACV), and anterior chamber angle (ACA) were measured by Pentacam and CASIA ...
